DIRECT AIR DISPLACEMENT-PUMP.

To all whom it may concern:

Be it known that I, JOHN RIGLING', citizen of the United States, residing at Philadel phia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Direct Air Displacement-Pumps, of which the following is a specification.

This invention relates to direct air disand belongs to that class of compressed alr water elevators wherein the inlet and exhaust valve for controlling the air served to the pump chambers is operated by a rocking contrivanoe set in motion without the employment of floats in the chambers and by means of the air.

his invention has for its object the production of rocking mechanism wherein a body of fluid mercury is shifted by a small portion of compressed air, from one side to the other of a pivotal support,causing the parts containing the mercury to rock, and at the same time operating the valvular de vice by which the mercury container or con-- duit is served the compressed air necessary to move the mercury as hereinafter explained.

The construction and arrangement of the parts of this invention are set forth in the accompanying drawings, of which Figure 1 represents a front view of all parts assembled. Fig. 2 is a vertical cross-section of one of the pump chambers. Fig.3 is a top plan view of the slide valve casing. Fig. 4 is a section lengthwise of the slide valve and easing on the broken line 44 of Fig. 3. Fig. 5 is a cross-section of the slide valve and casing on the broken line 5-5 of Fig. 3. Fig. 6 is a front view, slightly enlarged, of the air and mercury conduits and hollow terminals, partly in section. Fig. 7 is a vertical section of the air distributer or valvular device on the broken line 7-7 of Fig. 5. Fig. 8 is a cross-section of the air distributer on the broken line 88 of Fig. 7.

Throughout the drawings and description the same numbers are employed to refer to the same parts.

Considering the drawings, the pump chambers 1 and 2 have the discharge pipes 3 and 4 combined in an outlet 5, all of the customary construction. The pump chambers have connected with them the air pipes 6 and 7, which engage connections 8 and 9 of the slide valve casing 10. The slide valve, and the parts hereinafter described, are sup-- placement pumps,

wall or base plate 11, and the supplied with compressed air pipe 12 that engages'the connection 13 of the slide valve casing. A slide valve 14 has the ordinary cavity 15 and covers in its movement the ports 16, 17 and 18.

slid

Ports 16 and 18 are those admitting air to.

the pump chambers, and port 17 permits the air to pass into the exhaust passage 17. Valve 14 slides upon the table or 19, and is moved by the rod 20' that passes out of the casing by way of the stuffing box 21. The slide valve is held to its seat by the pressure block or cage 22, upon which pressure may be exerted by the screw 23 that extends upwardly through the top of the casing 10.

The valve rod 20 is worked in and out by a pivoted lever 24, which has a pin 25 sliding out and in a he lower end of the pin 25 is pivotally connected with the slide valve rod 20. The upper end of the lever 24 has a longitudinal bore 27 and pin 28 therein, similar in size, shape and disposition to the parts 25 and 26 just described, and the pin 28 is pivotally connected with an ear 29 of the rocking portion or member 30 of the air distributer. As best shown in Fig. 7, the distributer comprises the rocking external portion 30, having the annular flange or lip 31 projecting from its lower edge and engaging a corresponding recess in the rabbeted ring 32, by which the rocking portion 30 is movably held upon the support 33. The air distributer has also a stationary interior por tion or core composed of the upper cylinder 34, and the lower cylinder 35, the upper cylinder being held against rotation with respect to the lower by means of the connecting dowel pins 36 and 37. The rocking member is arranged concentrically with the station ary portion of the distributer. Compressed air may be supplied to the stationary portion of the distributer by the air pipe 38 connected With the main air pipe 12, as illustrated in Fig. 1. The air enters a cavity 39 in the cylinder 34, and by way of ducts 40 and 41 the air may enter the tube 42. the end of which is connected with the rocking portion of the airdistributer. The upper cylinder 34 of the stationary portion of the air distributer has a second duct similar to the duct 40, and at an angle therewith marked 43 and indicated in Fig. 6. This duct 43 may be brought to register with a in position.

the rocking portion 30 similar 41 and directly opposite to it In Fig. 7 theduct '44 is shown in communication with the exhaust duct 45 in the cylinder 34 and also port 46 formed through the top of the rocking portion 30' and registering with the exhaust the top of the rocking portion 30 is pierced by a second exhaust port 46 of similar size, and the cylinder 34 has also a second exhaust duct similar to the duct 45, but not shown, arranged to register with the exhaust port 46 The duct 44 in the rocking portion 30 is shown in communication with the tube 47. The: tubes usually occupy an inclined position as illustrated in Fig. (5', andit will be observed that the axes of those tubes pass through the center of the distributer. The outer end, andin Fig. 6 the lower end of the tube 42', is connected with the hollow, closed terminal receptacle 48, usually a hollow sphere, and the receptacle 48 carries a body of fluid-mercury 49. The receptacle 48 is connected as shown with the tube 51. the inner end of which is connectedwith the'rocking portion 30 of the distributer. Tubes 42 and 51 form one pair of tubesprojecting upon one side of the'rocking portion of the distributer. On the opposite side of the rocking portion, the spherical receptacle 50 connects the outer, and in Fig. 6 the upper ends of the tubes 4'7 and: 52, which comprise thesecond pair of projecting tubes. the tubes 47 thanthe tubes 51 and 52. The higher tubes. are the air conduits and the lower tubes the mercury conduits in this invention. assage 53 connects tubes 51, 52.

It is not intended to limit the size, length or'forms of the tubes or the terminals joining their outer ends.

The tubes and terminals rock with the rocking portion 30, and the rocking movement is limited and adjusted in degree by means of the projecting stops 54 and 54 carried by the rocking portion 30 of the dis.- tributer, which come into contact with the screws 55 and 56, best shown in Fig. 8.

In Fig, 1 it will be noted that the air pipeBS-has a valve 57, and the main air pipe a valve 58.

In Fig. 2 the water enters the pump chamber 2 by way of the check valve 59. and passes out into pipe 4 by way of the check valve 60, all of customary pattern and action.

By reason of the passage 53', tormed in the rocking portion 30, and permanently connecting the mercury conduits or tubes 51 and 52, those tubes may be held to constitute a single mercury conduit, pivoted in the middle.

The operation of this invention may be duct 44 in to the duct and 42 are higher in position with the'exhaust" cury duct 45. As shown-1 in Figs. 1, and 6 It will be observed that explained by assuming the parts to be in the positions shown. By way of the air pipe 38, cavity 3-9, and ducts '40 and 41, comdelivered inv pressed airenters tube 42 and is receptacle 48 above the surface of the mer- 49. The mercury is forced up through the lower tubes 51 and 52, the air leaving the tubesand receptacle 50 by way of the higher tube 47, ducts 44, 45, and exhaust port 46. hen sufiicient mercury has reached. the higher parts to overbalance the tubes, they rock and the receptacle 50 becomes 111.1139
